TOP VENT MEASUREMENTS
Vertical Rise
is calculated by measuring from the stove top to the top of the
Termination Cap (Vertical termination's),
and from the stove top to the
bottom of the vent on Horizontal terminations.
Horizontal Run
is calculated by
measuring from the closest edge of the starting section to the end of the
Termination Cap.
REAR VENT MEASUREMENTS
Vertical Rise
is measured from the top of the pipe exiting the stove to the top
of the termination cap (Vertical terminations.) or from the top of
the pipe
exiting the stove, to the bottom of the horizontal pipe run.
Horizontal Run
is
calculated by measuring from the back of the stove to the end of the
Termination Cap or elbow.
Each Pipe Joint takes off 1 1/2” when
assembled together.
For example,
a
four foot
and a 3 foot pipe together
would measure 6 feet 10 1/2”.
